Synthesis and Physiochemical Parameters of a Bio-Derived MgO Powder from Locust Beans Leaf Extract for Removal of Bod from Tannery Wastewater
Abstract
A study of the performance of BOD and physiochemical parameter degradation via adsorption was taken using Bio-derived MgO powder (MgO-p), synthesized using extract of locust beans and Mg (NO3)2 at 500oC following a green approach. The reduction efficiency of the MgO-p was evaluated in the presence of raw tannery wastewater by application of treatment time, adsorbent dosage, pH and concentration as parametric factors, and physiochemical properties such as TDS, EC, ORP and pH. Result obtained were compared to environmental regulatory limits (WHO and NESERA) on the reduction of biological oxygen demand (BOD) of wastewater from coffee processing plant using activated carbon made from Locust Beans extract with 99.02% and 99.35% removal at optimum operating conditions, percentage removal efficiency recorded ranged from a minimum of 5.71 to a maximum of 100 % at an initial concentration of 14.00 mg/l. Hence, the adsorption become constant and additional adsorbent made significant contribution. This study reveals that MgO powder is better applied as BOD reductants over physiochemical parameter for spent tan liquor.
